[LightDM] Building on XStreamOS/illumos

[Gabriele Bulfon]

We have our own illumos kernel fork on github, with customizations.
I may consider to change the delivered pam.conf to include my lightdm entries, once it works.
The problem here, I think is not yet about pam. It's not even arrived at pam calls yet.
LightDM just sits waiting for a SIGUSR1 from X never arriving....
I compared the code from lxdm (currently working, even pam), and I found this in lxdm, just
after spawing X:
g_message("add xserver watch\n");
for( i = 0; i
{
if(lxcom_last_sig==SIGINT || lxcom_last_sig==SIGTERM)
break;
if((s-dpy=xconn_open(display))!=NULL)
break;
g_usleep(50 * 1000);
//g_message("retry %d\n",i);
}
looks like a loop to check for a signal different from SIGINT||SIGTERM, and trying to XOpenDisplay
for some time, until it works or give up.
Maybe this is a fallback for SIGUSR1 not coming in?
Gabriele.

Thanks Guido,
our XStreamOS features recent xorg 1.14.5 as from oracle open repo.
I assume those issues you talk about are already present in this.
Do you think so?
I don't think there have been any changes, if you use XNV gate
from Oracle everything should still work as described in the
presentation I referenced, have a look at it, it even provides
links to the sdtlogin implementation.
I will definetly look at the gdm patch sets to see if and how they can fit into lightdm.
Anyway, XStreamOS Desktop does not include gdm at the moment (we would like to have lightdm instead).
So I don't have pam files for gdm.
Can you point me to some files to see around?
There are no pam files in Illumos, it only has a single static
/etc/pam.conf, see
http://src.illumos.org/source/xref/illumos-gate/usr/src/lib/libpam/pam.conf
So you either need to patch the PAM service names lightdm uses
and try to re-use the ones gdm uses or adapt pam.conf. The latter
would be a problem if you intended to create an IPS package of
lightdm, /etc/pam.conf is delivered by SUNWcs and there is no
way of amending it.
